IMPROVEMENT IN BOOK-COVERS.

specification forming part of Letters Patent No. 140,275, dated June 24, 1873; application tiled May 6, 1873.

To all whom it may concern:

Be it known that I, ALBERT H. J'OGELYN, of the city, county, and State of New York, have invented certain Improvements in Book- Covers, of which the following is a specification:

This invention relates to wrappers of paper or other suitable material for covering books; and consists, generally, in a novel manner of preparing. and folding the sheet of which both the sides and back of the cover are made, whereby great strength is insured where the cover is most liable to tear or break. The cover is readily and securely applied, and, although the back portion and sides of the cover are not made of separate pieces, facility is afforded for using the same-sized sheets to cover books of different sizes, and this with: out the aid of elastic strips or bands.

In the accompanying drawing, which forms part of this specification, Figure 1 represents a flat or face view of a sheet of paper prior to being treated and folded to make a book-cover. Fig. 2 is a similar view of thesame as folded to make the back and sides of the cover; Fig. 3, an edge view of the same; Fig. 4, a view in perspective thereof from the outer or back side, showing two rows of perforations to facilitate the partial rending of the sheet, and turning in the ends of the portion of which the back is composed, but before the folds in the sheet at the junction of the sides and back are laid down and secured by gum applied to said folds; Fig. 5, a like view to Fig. 4, but showing the gum as applied to the aforesaid folds and the ends of the back portion as torn ready to be turned in or folded over; Fig. 6, a view in perspective, showing the said folds as laid down and secured by the gum Fig. 7 a like view to Fig.6, but with certain portions rolled over and showing gum applied to the several corners on both sides of the sheet. Fig.8 is a view in ptrspective of my improved cover ready to be applied to a book or after such application and the book removed.

Similar letters of reference indicate correspondin g parts.

Fig. 1 represents a plain sheet of paper applicable to make one of several sized covers, according to the dimensions of the book to be protected. In this sheet I make two parallel the back of the book, while the remaining portions (1 d are the sides, used to cover the lid or sides of the book. These folds b b should be arranged at a suitable distance apart, so that when laid down or over they will receive within their nearest adjacent edges the back of the thickest book of a number of books of different sizes and width of back, such edges of said folds being 011 the outside of the cover. Figs. 2 and 3 illustrate this folding of the sheet distinct from other necessary treatment or preparation of it. Fig. 4 illustrates the same before the folds b b are laid down, and with parallel rows of perforations e 6 running from opposite. edges of the sheet across or partly across it in line with the outer or furthest distant edges of said folds after the latter have been laid over. The object of these perforations 6 e is to facilitate the rendin g of the back 0 from opposite ends, as represented in Fig. 5, to a given length of book, the back of which extends from the base of one of such torn portions to that of the other.

This rending of the prepared sheet is the only operation that requires particularity in applying said sheet as a cover to books of different lengths or sizes. In some cases these perforations may be omitted and the sheet simply be cut as required in the same lines, but 7 the perforating of the sheet as described gives hereinafter described, without the perforations in it, or a sheet merely having the gum applied to it, as hereinafter described, would be found a desirable acquisition for covering books.

The gum or adhesive matter is applied at any desired stage in the preparation of the FIG.

sheet or after the cover is partly or wholly fitted, and preparatory to pasting down the same, as follows, viz.: To the inner surfaces of the folds Z) I), which lie down on the back or bookback covering portion 0, as illustrated at h h, (seen more particularly in El g. 5,) and to either or both sides, but preferably to both sidesi k, of the sheets at its several corners.

To apply the cover to the book, the book is laid in the center of the sheet, the latter having the folds b b in it, as described. The sheet is then cut or torn in lines corresponding with the perforations e e to an extent or distance corresponding with the length of the book, and said torn or cut portions Z I turned over inward. The longitudinal exterior portions m m of the sides (I d are then turned over the inside faces of the lids of the book, and the extreme angles or corners nn of the end portions 0 o of the sides turned inward and cemented with the one guinmed side it of the corners of the sheet. The opposite gummed sides 6 of the corners of the sheet serve to secure the inner surfaces of the outer ends of the portions 1' 1' of the sides (I d of the sheet, which are turned down over the inside of the lids of the hook with the end portions 0 0, which latter are then turned down or over on the insides of the lids of the book,

and a port-ion of the gummed sides 7c of the corners made to adhere with the turned-over portions m m of the sides at d; also the gummcd portions 8 s of the folds b b, which lie beyond the ends of the back 0, are made to adhere firmly to the turned-in ends I Z of the back 0.

A book-cover thus made and fitted not only has its sides and back in one and the same piece, but is applicable to books of several sizes in all directions, is easily applied, forms a neat covering, and is strong, being braced by several thicknesses in the courses of the folds b b, where the cover is most liable to breakthat is, at the junction of the back with the sides of the cover.

What is here claimed, and desired to be secured by Letters Patent, is-

A book-cover having its back and sides in one piece and folded to give increased thickness and strength at or near the junction of such parts and provided with adhesive portions adapting it to be fitted to the sides an d back of the book, essentially as described.
